Not sure what guide you were following when doing all of your calibration, but plugging this here as one that has a lot of great information and might be something useful for you in the future. https://teachingtechyt.github.io/calibration.html
From what I can tell your K steps might not be in the most optimal spot and may need to be recalibrated among other things. Overall there are worse benchys, but it is useful to keep in mind that a benchy is a torture test and wont necessarily ensure results in your other prints. It would be useful to see what you are trying to print that is failing and using a more targeted test at that feature.
